We report the serendipitous identification of a low-mass (M* ? 2 × 106 M?), isolated, likely quenched dwarf galaxy in "foreground" COSMOS-CANDELS field. From deep Hubble Space Telescope (HST) imaging we infer surface brightness fluctuation distance for COSMOS-dw1 DSBF = 22 ± 3 Mpc, which is consistent with its radial velocity cz 1222 64 km s?1 via Keck/LRIS. At this distance, 1.4 Mpc projection...

background infertility is a serious social problem in advanced nations, with male factor in half of all cases of infertility. this study was conducted to determine the regenerative effect of bone marrow-derived stem cells in spermatogenesis of infertile hamster. methods twelve adult male hamsters were equally divided into azoospermic and control groups. busulfan was intraperitoneally used for i...

The aim of this study was to compare and analyze the site-specific accuracy of mixture of lipiodol and methylene blue (MLM) (0.6 ml, 1:5) and pure methylene blue (0.5 ml) on the rabbit lungs. In this study, CT-guided percutaneous injection of MLM and methylene blue. Compare the staining degree by biopsy of lung tissue. Use 4 points system to evaluate the site-specific accuracy at 6h and 24 h af...

We present the first results of a search for bright flashes associated to impacts of meteoroids on the surface of the night side of the Moon. We have analysed 13 sets of images of a (2.9±0.3) 106-km2-wide area on the Moon’s night side, totaling 4.3 h of observations. No impact events radiating an amount of energy higher than 5×106 J have been detected. Five fainter events (E < 2.5 × 106 J) have...

Glycosaminoglycans (GAGs), particularly heparin, are known to reduce the toxicities of various amyloidogenic proteins. The molecular factors underlying the antitoxic effects of GAGs, however, are still not fully understood. Because interactions of amyloidogenic proteins and their aggregates with membranes are believed to play major roles in affecting amyloid pathogenesis, our objective in this ...

The matrix (M) protein of Sendai virus (SeV) has five cysteine residues, at positions 83, 106, 158, 251, and 295. To determine the roles of the cysteine residues in viral assembly, we generated mutant M cDNA possessing a substitution to serine at one of the cysteine residues or at all of the cysteine residues. Some mutant M proteins were unstable when expressed in cultured cells, suggesting tha...
